Mu Ko Chumphon National Park

Mu Ko Chumphon National Park is a marine national park in Mueang Chumphon District, Chumphon Province, on the Gulf of Thailand. Established in 1989, it covers about 317 square kilometres including 40 islands, coral reefs, sandy beaches, mangrove forests and coastal hills. It is notable for clear waters, diverse marine life, and islands such as Ko Ngam Yai, Ko Ngam Noi and Ko Mattra, serving as a major conservation and recreation area in southern Thailand.

Visitors can expect a marine park comprising 40 islands scattered in the Gulf of Thailand, accessible by boat from the mainland. The setting includes white-sand beaches, limestone islets, coral reefs, mangroves and forested hills. Visitors can explore islands, swim and snorkel over reefs, take boat tours between islands, hike short trails to viewpoints, and visit the park headquarters and visitor centre at Hat Sai Ri. Facilities are basic and island access is weather-dependent.

Established in 1989 as Thailand's 44th national park and gazetted in 1999, Mu Ko Chumphon National Park was created to protect 40 islands, coral reefs, mangrove forests and coastal habitats in the Gulf of Thailand. It is managed by the Department of National Parks, Wildlife and Plant Conservation for marine conservation, research and regulated tourism.

The coastal area reflects traditional fishing communities of Chumphon Province and is located near the revered Prince of Chumphon Shrine at Hat Sai Ri, an important local cultural landmark associated with the founder of the modern Thai navy.
